Preventive Maintenance (PM) is a calendar drive or scheduled program. Based on prior experience. This is a time and/or operation count based maintenance where a piece of equipment gets maintained whether it needs it or not. This time based maintenance is labor intensive, ineffective in identifying problems that develop between scheduled inspections and is not cost effective.
- The care and servicing by personnel for the purpose of maintaining equipment and facilities in satisfactory operating condition by providing for systematic inspection, detection, and correction of incipient failures either before they occur or before they develop into major defects.
- Maintenance, including tests, measurements, adjustments, and parts replacement, performed specifically to prevent faults from occurring.
While preventive maintenance is generally considered to be worthwhile, it is important to note that there are risks such as equipment failure or human error involved when performing PM, just as in any maintenance operation. PM is also sometimes augmented by Reliability Centered Maintenance, which attempts to determine the best PM tasks, and by predictive maintenance, which models past behavior to predict failures.
To make it simple:
- Preventive Maintenance is conducted to keep equipment working and/or extend the life of the equipment.
- Corrective maintenance, sometimes called "repair", is conducted to get equipment working again.
